Lingo Reviews 

I ordered one month subscription for lingo twice. Each time one of the sensor turned out to be finicky. On my last order the sensor stopped working in less than 24hrs and it said to contact customer service.

The customer service is even worst. I sent them an email and after 48 hrs got a response saying apologizes for delay hope and we have addressed your concern. Which didn't make sense since they didn't even read the concern. I don't think I will order anymore product from them and I hope this feedback helps other folks to stop ordering from Lingo.

Getting access to data is utterly painful. Export produces several hundred 5-minute raw readings. Lots to excel work to produce barely useful data. No graphs to export. Customer Support staff barely trained.

I found it was not taking any readings during exercise. I used the Lingo CGM a s I was interested in my glucose levels especially on longer training runs. I’m a mature plodder, not an athlete. The sensor and my phone were within 20-30cm. I had no readings at all during these runs. The first and last readings showing were well within normal range, I didn’t feel depleted and I ate at intervals. I cannot believe I was so out of the normal range all the time not to provide a reading. I won’t buy another Lingo CGM again. Waste of money. I wish I had read the reviews beforehand.

The first one I purchased malfunctioned. I requested a replacement. After over a month of back and forth with customer service, I finally received the replacement. The application directions were ok, but I ended up using an online video for instructions. The warm up time was 24 hours. During this time, the device lost connectivity many times and required turn on & off my Bluetooth then restarting the phone. My readings have range 30 to 40 units below what my regular glucose monitor states.

Tried Lingo glucose monitor. Like it wanted to reorder. Order is repeatedly cancelled due to billing address being different than deliver address. Did not stop them from charging my debit card which still shows pending. Changed the delivery address to match billing address. Didn't work. Called and emailed repeatedly over a week. Spent hours with emails and talking to customer service. Promises made like " I have changed the address and it will go through" to "I've escalated to our finance pet and they will email or call you once the order is processed" not call no email...not one promise kept. Spent 26 minutes on phone last time only to have them put me on hold for 7 minutes then just disconnected. Absolutely horrible service. DO NOT BUY THIS PRODUCT not bc of the product but the customer service.

One of three sensors was faulty with horrible customer support. I decided to try them because I favored the “every minute” data that their system offered. I subscribed to a 3 month period, but for an unexplained reason on their part, they cancelled the order and they were not able to give me a timely explanation so that I could reorder. Their customer service absolutely does not care to rectify a problem.

The first sensor worked well. No complaints. The second failed immediately. I ran through all the troubleshooting steps. The device failed to connect. The error screen read ‘Biosensor ended early. Whatever the reason we’ll help you replace it.’ That was a lie.
Customer service has not responded to my emails. The phone number plays an obnoxious message about trouble shooting sensors that don’t work. No one picks up. No option to leave a message.

Never have a person write directions who was either part of the development team or trained by same. It appears they didn’t use focus groups to prefect its use for the common individual.

Most of the manual appears to be a lawyer’s dream job.

I personally hate the self serving , canned support dialogues.

Issues - I’m assuming that to see “yesterday” you push the yesterday arrow? How about reviewing your week? Got yesterday a few times. Good luck on past week. It would be nice if you could reliably pull up either or any beneficial data without being on the development team.

In short, providing a video link showing how to operate each step to open the various data information retrieval ports would be necessary. More importantly when it doesn’t open how to verify what’s wrong.

I’m going to try to save my 2 weeks, but I have no idea what it will look like or if I get it at all based on my experience with it thus far.

I looked online and here’s the product team director speaking too fast, sounding like a man selling a stolen car.

So I’m not impressed and I’m looking for another brand with better reviews.

I’ve just wasted an hour trying to place an order with Lingo.

I tried paying with multiple credit cards and the checkout/software repeatedly hangs, so the payment can’t be completed. What makes it worse is how difficult it is to get customer support — there’s no realistic way to get help when the system is failing.

In the end, I gave up and went elsewhere. The payment flow needs fixing, and customer support needs to be accessible.

My first biosensor stopped working within 24 hours. I got an error saying to contact them for a replacement. I have contacted them via support email and chatbot over 5 times in the last week and a half. Each time I got a confirmation acknowledging my email, and never heard back from anyone to send a replacement. It was a waste of $50 dollars, simply down the drain. If you’re considering using them, don’t.

Three emails concerning my first sensor (of two) falling off on the third day have gone completely unanswered prompting me to cancel my subscription. I used Levels/Dexcom for 2 years and any concerns (bad sensor, bleeding) were addressed promptly and satisfactorily. Unfortunately, Lingo is either too busy or doesn't care to respond.

I have been with Lingo for about 2 months. I ended up cancelling my subscription because I went through about 12 biosensors. They would work for a few days then quit. They will replace them but I just got tired of calling every few days. This should be pulled off the shelf and stop business

This review (a copy of the one I left on Hellolingo) relates to the Lingo continuous glucose monitor, which is basically a Freestyle Libre 2 repackaged as a commercially available product for non-diabetics to monitor their blood glucose. But my comments on the "stupid AI summary" relate to THIS space, because this is where an awful lot of people are leaving their reviews for the Lingo device, even though this page actually relates to an American 5G wireless company. Worked this out after I left the review, so I thought I'd drop a copy here for those who've also come to the wrong place. Search on Hellolingo for the actual product.

I'm so glad I didn't trust the stupid AI summary and used my human brain to analyze the ratings, because many of the one-stars relate to completely different products called Lingo or are clearly people who didn't follow the instructions. I'm on my third Lingo monitor now and have had no trouble at all, everything works just fine if you follow the instructions. I use a patch as a belt-and-braces measure but haven't even come close to knocking a sensor off yet, and when I remove the sensor after three weeks that thing has a death grip on my arm and will only come off with a persistent pulling motion. Almost painless to put on, no worse than taking off a bandaid when it comes off, the app isn't at all bad, and the insights I'm getting from monitoring my glucose are astounding. I'm too near the start of this "journey" to tell you much beyond that I've already changed the way I eat and feel a whole lot better, having gone from spiking my blood glucose up to the stratosphere several times a day to keeping it under reasonable control (try the Glucose Goddess if you don't know where to start). After a month, I already feel healthier and my clothes feel looser. I was going to put myself on Mounjaro to lose weight but I may not need to...and Lingo's a lot cheaper! This definitely takes the guesswork out of my quest to go from pre-diabetic to "normal".

I was very happy with the first biosensor I purchased, and it worked like a charm. when I went to replace it, with anew one it would not work: “biosensor incompatible.“ I thought perhaps it was a malfunctioning bio sensor so I used another one that I had purchased and same problem. I wasted two biosensors trying to get it to work. Each one was “biosensor incompatible.

Adil Ray is about the worst host you could pick for this show. He is patronising and has nothing original to say.

Adil is so patronising, makes me sick

It may be my own stupidity thinking it was possible but Lingo doesn’t make it clear that this device is a needle and not, as they say a “seamless fitting process”. I’m not good with needles anyway but have it a go and it bent as soon as it touched my skin. Lingo needs to update their website and sales page.

I’m 11 days in. There’s been a lot of broken contact although it appears to catch up from the “cloud” eventually - makes me suspect whether the trace is accurate. Also, the variability is low - not helpful visually. Anything from 5 to 7 pretty much looks the same; it’s a shame. Otherwise it was very helpful to confirm that my HB A1c was higher than it should be on a very low carb diet & despite a low fasting insulin. Useful to see how my body reacted to the food I ate including carbs x

This lingo was the best ever, it never stopped working, unless you go to far away from your phone then you loose connection.
It worked all the time, absolutely brilliant. It showed me that I can only eat very little sugar in a day, which is something I didn’t realise. Fabulous worked a treat, highly recommended, thank you.
Would 100% get again if I need.

I am halfway through a 28 day trial of Lingo continuous glucose monitor. Today I had connection problems which took a few hours to resolve and I found very frustrating.

I had to uninstall the Lingo app then reinstall it and go through the setup procedure once again.

I was originally trying to sort the procedure out by way of online chat. Luigi the technical support specialist asked me to look at the information from the online app and give him the information. However, unfortunately in doing this, I then lost contact with a Luigi on two occasions.

Eventually, I decided to phone but on this occasion, I will I was lucky and got through to speak with Paul in South Africa. Once again from my perspective as a 79-year-old man it wasn’t straightforward as I couldn’t hear some of his instructions from time to time.
